Whatโs the best way to add boat names ie do you paint them using a template or use stickers ?

Update - the 550 drill motor worked a treat on the 16.4v . I didnโt push it too hard and it still got pretty hot. I think 8.4v will be sufficient so thatโs my next test.
Turns out these old boats arenโt made from the best materialsโฆ.. the skin is leaking around the keel โน๏ธ which means the old circ 1960 ply is now wet inside my new paint. I should have epoxied it .

Yes , want it to go much faster - at least on the plane . I have wired up a 550 mabuchi motor from a 12v drill but i need to make sure i donโt cook it with the 16.4v

If I run a stock 12v 550 motor on 16.8v but at say 70% max throttle will I still cook the motor ?

Sea trials were a little underwhelming sadly . I have grossly underestimated the rpm of the traxxas titan 775 on 16.4v being 7,000rpm .
The result is a poultry speed as you can see.
So itโs back to the drawing board ๐
I need to find a 775 motor that can spin the 40mm prop much faster on 16.4v and get it on the plane at least.
Any ideas welcome .

Just the windows to go in and itโs ready for sea trials. Iโm going to try and cut up old cd cases unless anyone has better ideas for windows .
The traxxas 775 on 16.4 volts sounds very โtameโ so Iโm hoping I havenโt got a too low rpm set up . It has a 40mm prop

Thanks for your comment- a little secret is that the stripe is automotive min stripe ! Much easier and cleaner than painting and gives you a very clean edge. Also covers up an paint bleed ๐

Sharing a progress update on this sea rover.
I picked this boat up last year very cheap not knowing what Iโd do with it.
Its had a long 60-70 year life and at least two different colours being orange then navy - now blue and various engines from ic to electric.
It hasnโt been built to a high standard so Iโm having to work with what I have but Iโm really happy with the colour - it was nearly bottle green but i changed my mind last minute . I had to build the rear roof as well as replaced the gunwale and installed a chine rail too.
One concern is the bilge has not been water proofed or sealed which can only be accessed by major surgery.
The motor Iโve selected is a traxxas 775 titan swinging a 40โprop . Not sure if I will need 16.8v to get it moving which is what the motor is rated too.
Cheers

Can anyone help with replacement gears for the aquacraft ep-1 outboard.
Sadly Iโve worn mine out. They are made out of brass which isnt ideal. Manufacturing ceased a long time ago unfortunately.

Maiden voyage today - the speed controller I have selected over heated and it never got on the plane so Iโm going to wire up the traxxas evx2 which can handle bigger draw. I just need to remember how to โshot circuitโ one of the power inlets so it can run of the 12v lead acid.
Yes that battery is a bit heavy โฆ.

Need some deck fittings. Selec have them but the postage to
Australia is ยฃ17 which is the same price as the 3d printed parts .
Iโm considering Getting a 3d printer but I know nothing about them . If I do get them are the files downloaded and press print ? Is that how it works?
I canโt seem to find many options online .
Alternatively if someone wants to print them for me Iโm happy to pay .
Cheers

I used everyoneโs advice to get to this stage today - I went with 3 rails and removed the paint to stick them down . Soaked and steamed some .
Still need to trim the lower ones where they meet in the middle - not sure how Iโm going to finish them if I fair them flush with the hull .
These rails are Australian hardwood and were very difficult to work with . My fingers are full of splinters and ca glue but Iโm happy ๐

Yes - mine is 33โ. I think the rails need to be made from brass so they can be soldered . I tried soldering a coat hanger wire - didnโt work.

Thanks for this - I think I will take your advice and do 3 to keep it looking cleaner . So far Iโve wasted about 6m of hardwood for the gunwales and chine strips snapping but Iโm done now ๐
Side note where is a good place to get all the fittings for the deck ?

Made some progress - have since bolted the outboard on and with a 12v lead acid I think might be too heavy . I will give it a try once itโs all wired up and see how it runs. Iโm absolutely winging this build ๐

๐ FIRE TENDER POWER
2 years ago by
๐ฆ๐บ Schmango (
Petty Officer 1st Class)

I restored the same boat recently and installed two mabuchi 775 brushed motors via a single cheap eBay 480esc and 12v lead acid battery. Props are 50mm and it really moves however I had to add water cooling as I over heated one of the motors. Run time isnt that great though - maybe 10 mins . If you understand brushless and have the budget then that is the way to go I think. I didnโt want to spend much and donโt use it enough to justify the cost of brushless. I pulled the motors from an old hitachi drill!

๐ Vosper 46" fire boat motors and prop
4 years ago by
๐ฆ๐บ Schmango (
Petty Officer 1st Class)

Hi all - finally got to sea trial this today . The most notable issue is shaft alignment which is why it sounds like a two stroke engine . The 5mm shafts are very old and have some pitting in the metal which is strange. There is a small amount of play with them which Iโm guessing is causing the noise . The motors are cheap 700 size drill motors from eBay which do the job I think. Props are 45mm but I couldnโt find counter rotation in 5mm props so they are the same which isnโt a big issue.
Turning circle is terrible and it wants to nose dive even though the lead acid battery is towards the aft. Looking at other models of this boat it seems to be common though ? Is it normal to have the props and rudders a fair way apart as per the pictures?
I restored this model so I donโt know itโs history or age - it has definitely been built by an amateur and was possibly petrol powered once. Iโm guessing itโs from the 1970 era .
Overall itโs a great boat and Iโm happy with it .

Thanks for this info but I couldnโt find any 5mm - they are 4.8mm surely they are not the same ? Anyway I will have a look at drilling out a 4mm and using a lock nut . My concern drilling is getting it out of centre as I donโt have a drill press.

Hi - I have the motor thatโs in the pictures I posted - it has similar specs to a graupner 700 but is out of a leaf blower ๐คฃ.
I found an m5 45mm prop but not a counter rotation option so I will ha e to see how it goes with two right hand rotations . Anyone noticed much prop walk/ torque issues here ?
As a back up I have also purchased two 5mm to 4mm shaft couplings which are designed for motor to shaft applications but I might try and adapt them to the prop end by cutting an m4 screw for the prop end and attaching the prop that way if the props I have ordered donโt work.
Thanks for your help - itโs greatly appreciated
Cheers

Thanks Doug - I am running raboesch on my other model amd they are the best but this boat swinging 60mm props are going to be too big for 700 size motors I think.... ?
How do you go about re-bushing the shaft ? That might be a good option .
Appreciate your advice -very helpful

Hi all
Im getting close to finishing restoring this monster and im stuck with a few questions that I hope you can help with.
1) have have two 700 size motors which I want to run through a 480 amp esc with a 12v battery. Will that get it planing ok on 45mm props? am I going to blow it up?
2) the old boat has 5mm (M5) shafts and i cannot find a 5mm prop to go on the shaft. I dont have a lathe is there another way to reduce the props shaft to M4
3) Does anyone know where one can get 5mm (m5) props.
Cheers

Hi gents
I too have the same boat and have the same question . I only have shafts and rudders so I am looking for the whole package. I know little about brushless too but I think a boat like this needs them. From the research I have done I can see 880kv twins with 2 60 Amp water cooled esc will
Work. I would
Like to know what brand motors I need and what prop sizes to and esc brand to get. Iโd like 20 min run time too.
